Product features

The Mitsubishi S-N150 is a dependable non-reversing magnetic contactor from Mitsubishi Electric's MS-N series, designed specifically for direct on-line (DOL) control of three-phase cage motors. As a 3-pole industrial contactor with a 150A rated current, the Mitsubishi S-N150 performs well in a variety of industrial applications and meets international standards such as UL, IEC, and CCC. It is designed to handle numerous voltage levels, including 380-440V AC, and can support up to 75kW of rated power in AC-3 applications, making the Mitsubishi S-N150 an excellent choice for heavy-duty motor control operations.

The Mitsubishi S-N150, which comes standard with two normally closed (NC) and two normally open (NO) auxiliary contacts, increases the flexibility of control circuits in factories, power systems, and other industries. It employs mechanical lug connections for simple wiring and surface mounting, enabling for quick and trouble-free installation. What distinguishes the Mitsubishi S-N150 is its exceptional durability: it can survive up to 15 million mechanical operations and 1 million electrical operations for AC-3 applications, providing consistent performance even under heavy use.

The Mitsubishi S-N150's control coil provides numerous voltage options, including 100V AC, 200V AC, and 240V AC, to meet a variety of power supply needs. A built-in surge absorber protects the coil and control circuit from voltage spikes, thereby increasing operational safety. This Mitsubishi S-N150 magnetic contactor is ideal for use as a UPS input/output contactor, maintenance bypass contactor, or in motor control systems for pumps and fans.

Precautions

Follow these vital tips while installing and operating the Mitsubishi S-N150 magnetic contactor to ensure safe operation, a long service life, and consistent performance. First, place the Mitsubishi S-N150 in a dry, clean environment with temperatures ranging from -10°C to +40°C. Avoid placing it in regions with high humidity, dust, or corrosive gasses, since these can damage the contactor's internal components and impair its functionality. The Mitsubishi S-N150 is designed for surface mounting; ensure that the installation surface is firm and flat to avoid vibrations during operation, which might loosen wiring or damage components.

Before connecting wires, make sure the power supply voltage matches the coil voltage of the Mitsubishi S-N150; popular possibilities are 100V AC, 200V AC, and 240V AC. Using the wrong voltage will burn the coil or cause the contactor to cease to function. For wiring, use mechanical lug connections and tighten the terminals to avoid improper contact, which can result in overheating or electrical failures. Do not exceed the Mitsubishi S-N150's rated capacity: for AC-3 applications, it can handle up to 75kW at 380-440V AC and 150A rated current. Overloading the contactor reduces its service life and increases the chance of malfunction.

Regular maintenance is required for the Mitsubishi S-N150. Check the ordinarily open (NO) and usually closed (NC) auxiliary connections for wear and oxidation on a regular basis. If there is dirt buildup on the contacts, carefully clean them. If they are significantly worn, replace them. The Mitsubishi S-N150's built-in surge absorber protects the coil and control circuit; however, do not disassemble or modify this component without professional assistance. When combining the Mitsubishi S-N150 with a thermal overload relay, select the MS-T series for optimal compatibility, since this creates a full and dependable motor protection system.

FAQ

Q: How does the Mitsubishi S-N150 connect and communicate within a control system?

A: The S-N150 servo amplifier primarily communicates over CC-Link IE TSN. This enables it to link directly to a master station (such as a Mitsubishi Electric PLC) via a single, high-speed network that can handle both motion control and standard I/O data in precise synchronization. This simplifies wiring, lowers costs, and improves system performance when compared to typical pulse-train or separate network systems.

Q: What are the compatible motors for the Mitsubishi S-N150 servo amplifier?

A: The Mitsubishi S-N150 is a component of a matched system. The "S-N150" model usually refers to a particular amplifier and motor combo. It is designed to function best with the MELSERVO-J5 series servo motors, which come in a variety of power ratings and inertia kinds. The correct motor for the S-N150 must be chosen based on torque, speed, and load inertia requirements utilizing Mitsubishi's sizing tools or technical publications.

Q: How do I program and configure the Mitsubishi S-N150?

A: The Mitsubishi S-N150 servo drive is commonly configured and tuned using MR Configurator2, a dedicated software application developed by Mitsubishi Electric. This Windows-based software enables engineers to configure parameters, perform auto-tuning, monitor operating status, and diagnose problems using a linked PC. Parameters can also be set using the network master PLC.
